$(g-2{)}_{e,\mu }$ and Lepton flavor violating decays in a left-right model

Abstract

General expressions for one-loop contributions associated with lepton-flavor violating decays of the standard model-like Higgs boson $h\to e_b^{\pm }{e}_a^{\mp }$ and gauge boson $Z\to e_b^{\pm }{e}_a^{\mp }$ are introduced in the unitary gauge. The results are used to discuss these decays as new physics signals in a minimal left-right symmetric model containing only one bidoublet Higgs and a $SU(2{)}_R$ Higgs doublet accommodating data of neutrino oscillations and $(g-2{)}_{\mu }$. The numerical investigation indicates that some of these decay rates can reach near future experimental sensitivities.
